How is STPP made?
STPP has been normally made by a process that includes the steps of (a) reacting a sodium compound such as soda ash (Na 2 CO 3) or caustic (NaOH) with either wet process phosphoric acid or furnace process phosphoric acid to form a reaction mixture containing monosodium phosphate (NaH 2 PO 4) and disodium phosphate (Na ...
What can I use instead of STPP?
Sodium silicate(powder, lumps,liquid)… Complex Sodium Disilicate is the best in current phosphorus-free detergent builders, the function is almost same as STPP. It is the best replacement of STPP at present. Complex Sodium Disilicate is completely friendly to each while STPP caused serious pollution.
Is STPP a foaming agent?
Sodium tripolyphosphate is used in a variety of cleaning products. It improves the ability of various ingredients in the detergent to penetrate the fibers of clothes (as well as other surfaces and materials to be cleaned) more deeply, and aids in foaming and bubbling.
What is the pH of STPP?
Sodium tripolyphosphate is a binder, stabilizer, and sequestrant that is mildly alkaline, with a pH of 10, and moderately soluble in water, with a solubility of 15g in 100ml of water at 25°C.
Why is sodium tripolyphosphate no longer used as a detergent additive in the United States?
Uses. Sodium tripolyphosphate was an excellent builder used in laundry detergent powders. However, due to issues of biodegradability many countries have banned the use of phosphates in detergents. Manufacturers are using substitutes such as EDTA and other biodegradable chemicals instead.

What is the meaning of STPP?
Definition of sodium tripolyphosphate : a crystalline salt Na5P3O10 that is used as a food additive and as a component in some detergents and is suspected of contributing to water pollution.
How do you dissolve a STPP?
Weigh out 2.5 g of sodium tripolyphosphate. In a 150-ml acid-washed beaker, dissolve the sample in 100 ml of deionized distilled water. Under a hood, acidify the solution with concentrated HNO3 to a pH of less than 2. Gently heat the solution to reduce the volume below 100 ml, making certain that it does not boil.

What is the use of trisodium phosphate?
Trisodium phosphate has a variety of applications but is primarily used as a cleaning agent, food additive, stain remover and degreaser. Accepta's trisodium phosphate is a white, granular or crystalline solid, highly soluble in water producing an alkaline solution.
Why STPP can be used in detergent
Hydration performance. At room temperature, stpp chemical is quite stable, and it will slowly undergo hydrolysis in humid air, eventually producing sodium orthophosphate. Under the same conditions, the high-temperature type hydration generates high heat quickly and is prone to agglomeration when dissolved in water.
The Function of STPP in Synthetic Detergents
The main ingredients of synthetic detergents are surfactants. The surface active agents have wetting effect, penetration effect, emulsifying effect, dispersing effect and foaming effect, etc… Decontamination is a comprehensive result of these effects.
